New Galileo Open Service Signal-In-Space Operational Status Definition Document

The document is divided into three sections:

• A comprehensive guide on how the status of the Galileo SIS is disseminated by the signal itself through specific data within the Navigation Message
• Important information on the use of navigation parameters, recalling the reference for the ionospheric model used by Galileo
• Additional information on the validity of navigation parameters.

A public consultation on the document will open next week.
